SIDE TROUGHING-BOLL FOR BELT CONVEYERS.

Specification of Letters Patent.

Patented Aug. is, 1912.

application filed April 24, 1912. Serial No. 892,793.

T 0 all whom it may concern.

Be it known that I, EDWARD CUnmnr, citizen of the United States,residing at Tocele, in the county of Tooele and State of Utah, haveinvented certain new and useful Improvements in Side Troughingllolls forBelt Conveyers, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention has relation to improvements in side troughing rolls orpulleys for belt-conveyors; and it consists in the novel details ofconstruction more fully set forth in the specification and pointed outin the claims.

In the drawings, Figure 1 is a side elevation of a portion of abelt-conveyer showing my invention applied thereto; Fig. 2 is across-section through the upper lap of the belt, showing a sideelevation of my invention, and carrier therefor, parts being in section;Fig. 3 is an end view of the side troughing pulley; and Fig. 4 is alongitudi nal middle section on the line 4-4 of Fig.

The present improvement is particularly directed to the side troughingrolls for belt conveyors and has for its object to provide a roll whichwill insure a direct travel of the belt without the objection of lateralsway or displacement thereof under a load, the roll at all times actingas a guard bearing on the edges of the belt, and constraining the latterto adhere to its prescribed course. The roll further serves to maintaina positive trough in the upper belt-lap as will be fully apparent from adetailed description of the invention, which is as follows:

Referring to the drawings, B represents an endless belt operating inconjunction with a series of troughing roll carriers, C, one of theterminal pulleys P over which the belt asses, and a portion of the chuteD whic discharges the material onto the belt being here illustrated in aconventional way, no claim being made to these features. The troughingrolls or pulleys usually comprise a series of intermediate cylindricalmembers 1, and suitable side members, and the return rolls comprisecylindrical members 2, as well understood in the art.

In the present improvement the side members of the troughing rollscomprise each a cylindrical body portion 3 or roll proper, and an outerflaring head or flange 3 formed integrally with the portion 3. Theflange 3 is preferably conical, the elements of the peripheral surfacethereof being inclined sul'istantially at an angle a of thirty degreesto a plane at right angles to the axis of the body portion 3, or at anangle of sixty degrees to said axis. In practice, the side rolls aremounted on spindles 4 inclined at an angle a of thirty degrees to thehorizontal, whereby the vertical element of the conical surface of theflange 3', bearing iminediately against the edge of the belt B, will liein a plane disposed at right angles to the plane of travel of the belt.Thus in Fig. 2 the element 0 engaging the edge of the belt is verticalor lies in a vertical plane, the belt traveling in a substantiallyhorizontal plane. 'Duringlthe rotation of the side roll there willalways be an element of the conical peripheral surface of the flange 3disposed at right angles to the horizontal plane of travel of the belt,thus serving as a guard for the belt and preventing lateral shiftingthereof. The edges of the belt (or web) will accordingl be constrainedto take the course prescribed for them by the positions of the siderolls, and no deviation from such course is possible, the flanges 3' atall times serving as positive side guards over which the belt can notclimb or creep. The angle of thirty degrees defining the flare of theheads or flanges 3 need not necessarily be adhered to, and if changed, acorresponding change in the dip of the spindle 4 would obviously benecessary in order to bring the top element of the cone, or thatengaging the edge of the belt to a vertical, or into a plane at rightangles to the horizontal travel of the belt. true conical surface (forthe flange 3') is the most desirable, as the elements composing it arestraight lines, although I wish to include within the scope of myinvention, any flaring head which will operate as an equivalent.

The distinctive character of the side roll here described is that itcomprises two distinct portions, to-wit, the portion 3 for the supportof the side of the belt, and the portion 3' for guarding the edge of thebelt.

Having described my invention what I claim is 1. In combination with aconveyor belt, a side troughing roll comprising a body ortion for thesupport of the side of the elt, and a terminal conical flangeor beadflaring outwardly for engaging the edge of the belt.

2. In combination with a conveyer belt, a

I side (roughing roll comprising a cylindrical body portion over whichthe side of the belt travels and by which it is supported, and aterminal conical flange bearing.against the edge of the belt,the saidroll being mounted to ermanently present an element of its conicalsurface into a plane disposed substantiall .atright angles to the planeof travel 0 the belt.

3. In combination with a'eonveyer belt, a side troughing roll having aconical forma- In testimony whereof I afiix my signature, in presence oftwo witnesses.
